Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, so the safety profile is known. The description usefully adds the two-phase approval gate and the requestId reuse requirement, but the sentence 'Claim live only when status is active' is opaque — it is unclear what 'claim live' means or what happens if status is not active, leaving a destructive operation partly unexplained.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The purpose is front-loaded and the approval rule follows logically, with no padding in the first three sentences. The trailing 'Fields: soclo://...' sentence earns nothing — it is a dangling reference that consumes space without adding information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive, open-world mutation with no output schema and a nested payload, the description covers the confirmation gate but says nothing about what a successful update returns, what happens on an unconfirmed call, or where to poll status. An agent could call it correctly but not recover cleanly from failure.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 60%, and the ten payload fields (name, status, category, countingType, defaultValue, lookback windows, etc.) carry no descriptions anywhere. The description's only attempt to document them is 'Fields: soclo://tools/soclo_ads_update_conversion_action', a self-referential pointer that conveys no field meaning, so the coverage gap is not compensated.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and resource ('Update a conversion action's settings'), which cleanly separates it from siblings like soclo_ads_create_conversion_action and soclo_ads_list_conversion_actions. It stops short of naming those siblings explicitly, so differentiation relies on the reader knowing the naming convention.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

'Spending/deletion: preview, then owner-approved confirm:true with the same requestId' gives a real prerequisite for the confirm flag, which is more than most update tools offer. However, it never says which tool performs the preview or points to soclo_ads_operation_status for the outcome recovery that requestId is described as enabling, so the workflow is implied rather than routed.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
